As you can assume, I'm fairly familiar with the "standard" flow objects
appearing in the DSSSL fot. The sosofos do never come up to this point, and
as I thought, the formatting backends need to render the contents of the

So I looked at the standard about "indirect sosofos" and found some infos
layout-driven generated Text, which is even currently implemented for
page-numbers and could easily be enhanced to support per-page footnotes and
the like.

Yet, I don't see the needs for bidirectional communication here - could you
please specify that? Furthermore, is this feature implemented in OpenJade
yet? Do you have examples for the usage of it?
